Abstract (en)

The present disclosure provides a cleaning assembly including a cleaning performing device. The cleaning performing device includes a cleaning module configured to clean a surface and a cleaning driving module configured to drive the cleaning module to move relative to the surface, a driving device configured to drive the cleaning performing device to be lifted or lowered, and a constraining structure configured to constrain a lifting or lowering trajectory of the cleaning performing device. The present disclosure further provides a cleaning apparatus. The cleaning performing device can be lifted or lowered according to an actual need, such that improves an adaptability of the cleaning apparatus. Further, the lifting or lowering trajectory of the cleaning performing device can be constrained by the constraining structure, such that improves a stability of the cleaning apparatus during moving up and down.
